Restore permission check for mic muting
The implementation for AudioManager.setMicrophoneMute() used to
call directly into AudioSystem which called directly into
AudioFlinger and the mediaserver process, where the check for
the MODIFY_AUDIO_SETTINGS is performed.
A regression was introduced by Ib32138bcc256cfbac4fe21a090d5ba34f5c641fc
which calls first into AudioService which runs in system_process
before calling into AudioSystem, which granted the permission.
This CL adds a permission check in this code path when calling
AudioService.
